FIELD

Aspects described herein generally relate to light-emitting diode (LED)light sets. More specifically, aspects relate to changing the coloremission of LED light sets.

BACKGROUND

The use of light sets as decorations for holidays such as Christmas andHalloween is conventional. However, in most instances, such lights areonly capable of emitting light in a single holiday-specific colorarrangement in accordance with the traditional colors of the holiday(e.g., red, green, etc. for Christmas, orange for Halloween, and thelike). Accordingly, decorative light sets need to be swapped out betweenholiday seasons to ensure cohesion with holiday color schemes.

In other instances, complex light strips may be able to achieve varyingspectrums of light emission. While such strips may enable assimilationwith traditional color arrangements of a multitude of holidays, theyrequire expensive RGB color LEDs, extra wiring to each LED to allow forcontrollability, a microcontroller to dictate color emission of theLEDs, and a remote control to engage with the microcontroller to enableuser control over the light emission.

Accordingly, there exists a need for ways to change the color emissionof LED light sets in a less expensive and simple fashion.

FIG. 1 illustrates an LED 100 that may be used according to one or moreillustrative embodiments of the disclosure. LED 100 may be a miniature,low-current, low-power, standard, ultra-high-output, high-power, ACdriven, flashing, bi-color, tri-color, decorative-multicolor, orfilament LED depending on the embodiment. LED 100 may include LED chip102A, LED chip 102B, casing 104, anode terminal 106, and cathodeterminal 108. In some instances, LED 100 may include additional LEDchips, anode terminals, and cathode terminals similar to LED chip 102Aor 102B, anode terminal 106, and cathode terminal 108.

LED chips 102A and 102B of LED 100 may be solid-state semiconductordevices configured to convert electricity into specific wavelengths oflight. LED chips 102A and 102B may be made of any of a number ofsemiconductor materials including gallium arsenide, aluminum galliumarsenide, gallium arsenide phosphide, aluminum gallium indium phosphide,gallium (III) phosphide, aluminum gallium phosphide, indium galliumnitride, gallium (III) nitride, zinc selenide, silicon carbide, silicon,diamond, boron nitride, aluminum nitride, aluminum gallium nitride,aluminum gallium indium nitride, and the like. Such semiconductormaterials may be used alone, or in combination. Additionally, thesemiconductor materials may be coated and/or wrapped in phosphor orplastic to produce additional wavelengths/colors of light. In someinstances, other types of materials may be used.

Depending on the types of semiconductor materials of LED chips 102A and102B, the chips may be configured to emit wavelengths of lightcorresponding to infrared, red, orange, yellow, green, blue, violet,purple, ultraviolet, pink, white, or combinations thereof. Accordingly,LED chip 102A may be made of a first material and may be configured toemit a first wavelength of light and LED chip 102B may be made of asecond material different than the first material and may be configuredto emit a second wavelength of light different than the first wavelengthof light. For example, LED chip 102A may be made of gallium (III)phosphide and may be configured to emit green light and LED chip 102Bmay be made of gallium arsenide phosphide and may be configured to emitorange light. In certain embodiments, LED chips 102A and 102B may bemade of the same material and may be configured to emit the samewavelength of light.

LED chips 102A and 102B may be connected in series with a same polarityand may be configured to emit light simultaneously (e.g., both LED chip102A and 102B are activated and/or powered on and emitting light at thesame time). Alternatively, LED chips 102A and 102B may be connected inseries with an opposite polarity and may be configured to emit light inthe alternate (e.g., when LED chip 102A is activated and/or powered onand emitting light, LED chip 102B is not activated and/or powered on andnot emitting light).

In instances where additional LED chips 102 are included in LED 100,each LED chip of a plurality of additional LED chips may be connected inseries with the same polarity and may be configured to emit lightsimultaneously (e.g., all LED chips of the plurality of LED chips in LED100 are activated and/or powered on and emitting light at the sametime). Alternatively, each LED chip of a plurality of additional LEDchips may be connected in series with alternating polarity and may beconfigured to emit light in the alternate (e.g., every other LED chip ofthe plurality of LED chips in LED 100 are activated and/or powered onand emitting light). Furthermore, the plurality of LED chips may begrouped in alternating like-polarity increments and may be configured toemit light in the group alternate (e.g., every other group of three LEDchips of the plurality of LED chips in LED 100 are activated and/orpowered on and configured to emit light at the same time). Suchgroupings of LED chips may be symmetric or asymmetric depending on theembodiment.

LED chips 102A and 102B may be attached to casing 104. Casing 104 may bemade of any one, or combination of, metals, polymers, ceramics, and/orcomposites. In some embodiments, casing 104 may encapsulate LED chips102A and 102B. In such embodiments, casing 104 may be either waterproofor non-waterproof. Furthermore, casing 104 may be colored and, as such,may be configured to alter the end light emission spectrum. In otherembodiments, casing 104 may be a surface to which LED chips 102A and102B are attached and may not encapsulate the chips.

LED 100 may be a polarized component and may include anode terminal 106and cathode terminal 108. Anode terminal 106 may be alternativelyidentified as a positive terminal and may be configured to receive apositive voltage input. Cathode terminal 108 may be alternativelyidentified as a negative terminal and may be configured to receive anegative voltage input. However, in certain embodiments, terminals 106and 108 may be identified as a first terminal and a second terminal,respectively, and may be configured to receive either a positive ornegative voltage input.

As shown in FIG. 2, LED chip 102A may be configured to activate and/orpower on and emit a first wavelength of light when power flow A entersLED 100 through first terminal 106. Conversely, LED chip 102B may not beconfigured to activate and/or power on under such a direction of powerflow. In some embodiments, both LED chips 102A and 102B may beconfigured to activate and/or power on when power flow A enters LED 100through first terminal 106. Alternatively, both LED chips 102A and 102Bmay not be configured to activate and/or power on under such a directionof power flow.

As shown in FIG. 3, LED chip 102B may be configured to activate and/orpower on and emit a second wavelength of light different than the firstwavelength as discussed above when power flow A enters LED 100 throughsecond terminal 108. Conversely, LED chip 102A may not be configured toactivate and/or power on under such a direction of power flow. In someembodiments, both LED chips 102A and 102B may be configured to activateand/or power on when power flow A enters LED 100 through second terminal108. Alternatively, both LED chips 102A and 102B may not be configuredto activate and/or power on under such a direction of power flow.

FIG. 4 illustrates an LED system 400 according to one or moreembodiments of the present disclosure. LED system 400 may include one ormore LEDs 100, each of which including the above-mentioned components(e.g., at least LED chips 102A and 102B, casing 104, at least firstterminal 106 and second terminal 108), wire 200, and power terminal 300.

Each of the one or more LEDs 100 may be connected in series to eachother via wire 200. The first and last LEDs 100 of the series of LEDsmay be connected to power terminal 300 via wire 200. Accordingly, wire200 may be configured to connect power terminal 300 to each of the LEDs100 in the series of LEDs in a loop. Wire 200 may be a wire, string,and/or cable and may be comprised of any of a plurality of conductivematerials including, but not limited to, copper and aluminum. Wire 200may be an insulated wire or may be an uninsulated wire depending on theembodiment. Furthermore, wire 200 may be a rigid, semi-rigid, orflexible wire allowing for pliability, or lack thereof.

In certain embodiments, wire 200 may contain a first terminal end 202and a second terminal end 204. The first terminal end 202 and secondterminal end 204 may be configured to be plugged and/or unplugged from apower output portion 302 of power terminal 300. Accordingly, thepolarity of wire 200 may be reversible by interchanging the connectionof the first terminal end 202 and second terminal end 204 with a poweroutput portion 302 of power terminal 300 as will be discussed in furtherdetail below. In certain embodiments, the first terminal end 202 may beknown as a first inline connector, and the second terminal end 204 maybe known as a second inline connector.

Power terminal 300 may be configured so as to provide electrical energyto the one or more LEDs 100 of LED system 400. Power terminal 300 mayinclude solar panels/cells mounted thereon so as to translate solarenergy into electrical energy for storage in the power terminal 300. Inother embodiments, power terminal 300 may include one or moreexhaustible batteries, one or more rechargeable batteries (e.g., 18650Lithium Ion batteries or other suitable rechargeable batteries), or thelike. In some instances, the power terminal 300 may be connectedindirectly to an AC power source via a power transformer (not shown).The power transformer may be integral with power terminal 300 or may bean ancillary adapter. The power transformer may be able to translateenergy into a form acceptable by the one or more LEDs 100. Such energysources and/or translation methods may be used alone, or in combination.

As stated above, the power terminal 300 may be configured to engageand/or disengage with the first terminal end 202 and the second terminalend 204 of wire 200. Accordingly, power terminal 300 may be configuredto output power through either the first or second terminal enddepending on the orientation of engagement/polarity of the terminal endsof wire 200 relative to a power output portion 302 of power terminal300. For example, in instances where the first terminal end 202 of wire200 is engaged with the power output portion 302 of power terminal 300,power flow A may flow through the first terminal end 202. Alternatively,in instances where the second terminal end 204 of wire 200 is engagedwith the power output portion 302 of power terminal 300, power flow Amay flow through the second terminal end 204. In such instances, poweroutput portion 302 may be a fixed and/or static power output portion.

In certain embodiments, power terminal 300 may further include A/Bswitch 304 which can be used to reorient power output portion 302 andreverse the direction of power flow A into wire 200 from the firstterminal end 202 to the second terminal end 204 or vice versa. In suchembodiments where power terminal 300 includes A/B switch 304, the firstand second terminal ends of wire 200 may be rigidly attached to powerterminal 300 and power output portion 302 may be an alterable and/ordynamic power output portion. However, the first terminal end 202 andsecond terminal end 204 of wire 200 may be configured to engage and/ordisengage with power terminal 300 in addition to the presence of A/Bswitch 304.

Depending on the direction of power flow A from power terminal 300, oneor more LED chips comprised within the one more or more LEDs 100 mayactivate and/or power on and emit light. For example, as shown in FIG.4, when power flow A enters the first terminal 106 of one or more LEDs100, LED chips 102A may activate and/or power on and emit light of afirst wavelength (e.g., red). In certain embodiments, the LED chips 102Aof each of the plurality of LEDs 100 may exhibit any of a range ofwavelength profiles (e.g., red, green, blue, yellow, white, etc.). Thepattern of wavelength profiles for the LED chips 102A of each of theLEDs 100 connected in the series of LEDs may be homogeneous (e.g., red,red, red, red, etc.), heterogeneous and symmetric (e.g., red, red,yellow, yellow, green, green, etc.), heterogeneous and asymmetric (e.g.,red, red, yellow, green, blue, blue, orange, white, etc.), orheterogeneous and random (e.g., red, green, blue, purple, yellow, etc.).

As shown in FIG. 5, when power flow A enters the second terminal 108 ofone or more LEDs 100, LED chips 102B may activate and/or power on andemit light of a second wavelength different than the first wavelength.In certain embodiments, the LED chips 102B of each of the plurality ofLEDs 100 may exhibit any of a range of wavelength profiles (e.g., red,green, blue, yellow, white, etc.). The pattern of wavelength profilesfor the LED chips 102B of each of the LEDs 100 connected in the seriesof LEDs may be homogeneous (e.g., blue, blue, blue, blue, etc.),heterogeneous and symmetric (e.g., blue, blue, orange, orange, purple,purple, etc.), heterogeneous and asymmetric (e.g., blue, blue, orange,purple, yellow, yellow, green, white, etc.), or heterogeneous and random(e.g., red, green, blue, purple, yellow, etc.).

Through reversing the polarity of the terminal ends of wire 200 relativeto the power output portion 302 and/or reversing the direction of powerflow A into wire 200 via actuation of A/B switch 304, at least twodifferent color patterns may be realized. For example, as describedabove in regards to FIG. 4, when power flow A enters the first terminal106 of one or more LEDs 100, LED chips 102A may activate and/or power onand emit light of a first wavelength and/or first range of wavelengths.The first wavelength and/or first range of wavelengths may be associatedwith a first color pattern of, for example, a first season (e.g.,spring, summer, fall, winter) or holiday (e.g., Fourth of July,Halloween, Easter, Christmas, etc.). Conversely, as described in regardsto FIG. 5, when power flow A enters the second terminal 108 of one ormore LEDs 100, LED chips 102B may activate and/or power on and emitlight of a second wavelength and/or second range of wavelengthsdifferent than the first wavelength and/or first range of wavelengths.The second wavelength and/or second range of wavelengths may beassociated with a second color pattern of, for example, a second seasonor holiday, wherein the second color pattern is different than the firstcolor pattern.

Alternatively, the LED chips 102A and 102B of LEDs 100 may berespectively configured to emit one of colored or non-colored light. Forexample, when power Flow A enters the first terminal 106 of one or moreLEDs 100, LED chips 102A may be configured to emit white light. However,when power flow A enters the second terminal 108 of one or more LEDs100, LED chips 102B may be configured to emit colored light (e.g., red,orange, yellow, green, blue, purple, etc.). In the manner describedherein, reversing the polarity of wire 200 relative to power terminal300 and/or reversing the direction of power flow A into wire 200 viaactuation of A/B switch 304 allows for at least two different lightpatterns to be achieved.

While not explicitly shown in FIG. 4 or 5, A/B switch 304 may include atimer. The timer of A/B switch 304 may be any one of a mechanical,electrical, or electromechanical timer and may be configured to turnon/off at a specified time for a specified time interval (e.g., turn onfor one hour starting at 8 PM, turn off for eight hours starting atmidnight, etc.). The time and time interval may be specified by a user,or may be predetermined. Alternatively and/or additionally, the timermay be a 24 hour timer and may be configured to turn on/off at aspecified time for a specified time interval each day (e.g., everydayturn on for five hours starting at 6 PM). In some instances, multipletimes and time intervals may be set.

In certain embodiments, the timer may be configured to terminate powerflow A from power terminal 300 to wire 200 during either the on or offperiod. For example, the timer may be set by a user and/or may bepredetermined to turn on for an eight hour period starting at 7 PM.During the time period in which the timer is off (e.g., 3 AM to 7 PM),the timer may be configured to inhibit power flow A from power terminal300 to wire 200, and thereby prevent light emission from the one or moreLEDs 100. Conversely, during the time period from 7 PM to 3 AM in whichthe timer is on, the timer may be configured to allow power flow A fromterminal 300 to wire 200, and thereby allow light emission from the oneor more LEDs 100.

In other embodiments, the timer, in conjunction with A/B switch 304, maybe configured to reorient power output portion 302 and reverse thedirection of power flow A into wire 200 from the first terminal end 202to the second terminal end 204 or vice versa at a specified time for aspecified time interval. For example, the timer may be set to turn onfor a three hour period starting at 6 PM. During the period in which thetimer is off (e.g., from 9 PM to 6 PM), the timer may be configured tocause A/B switch 304 to orient power output portion 302 in line with thefirst terminal end 202 and cause power flow A to enter wire 200 throughthe first terminal end 202. During such a time period, each of the LEDchips 102A of the one or more LEDs 100 may be configured to activateand/or power on and emit light of a first wavelength. Conversely, duringthe time period from 6 PM to 9 PM in which the timer is on, the timermay be configured to cause A/B switch 304 to reorient power outputportion 302 from the first terminal end 202 to the second terminal end204 and cause power flow A to enter wire 200 through the second terminalend 204. During such a time period, each of the LED chips 102B of theone or more LEDs 100 may be configured to activate and/or power on andemit light of a second wave length different the first wavelength.

FIG. 6 depicts an LED string 600 according to one or more aspects of thedisclosure. LED string 600 may be configured for indoor and/or outdooruse and may be configured to be hung from any of a plurality of objectsincluding, but not limited to, a house façade, tree, bush, door frame,wall, ceiling, and the like. LED string 600 may include one or more LEDs100, each of which comprising the above-mentioned components (e.g., atleast LED chips 102A and 102B, casing 104, at least first terminal 106and second terminal 108), wire 200, and power terminal 300.Additionally, each component of LED string 600 may have some or all ofthe structural components described above in regard to LED system 400.

Wire 200 may be a thermoplastic sheathed electrical wire and may beconfigured to form a waterproof seal with the first terminal 106 andsecond terminal 108 of each of the one or more LEDs 100. In certainembodiments, wire 200 may be fixedly attached to each of the one or moreLEDs 100. However, in other embodiments, wire 200 may be configured tobe attached and/or detached from each LED 100 in LED string 600.Accordingly, each of the one or more LEDs 100 may be removable and/orreplaceable. For example, if an LED 100 ceases to emit light, the LED100 may be removed from LED string 600 and replaced with a new and/orfunctioning LED. Similarly, if a segment of wire 200 fails, theparticular segment may be detached and/or replaced in LED string 600. Incertain embodiments, segments of wire 200 including one or more LEDs 100may be added and/or removed from LED string 600 so as to increase and/ordecrease the overall length of LED string 600.

The LEDs 100 of LED string 600 may be of a similar type (e.g.,miniature, low-current, low-power, high-power, flashing, bi-color,tri-color, etc.) or may be any of a range of types. The pattern of LEDtypes of the LEDs 100 of LED string 600 may be homogeneous (e.g.,high-power, high-power, etc.), heterogeneous and symmetric (e.g.,flashing, high-power, high-power flashing, etc.), heterogeneous andasymmetric (e.g., high-power, high-power flashing, bi-color, tri-color,tri-color, high-power, flashing, etc.), or heterogeneous and random(e.g., high-power, flashing, bi-color, tri-color, etc.).

While not explicitly shown in FIG. 6 and FIG. 7, LED chips 102A and 102Bmay be included within the one or more LEDs 100. The LED chips of theone or more LEDs 100 may be configured to activate and/or power on whenpower flow A traverses wire 200. For example, when power flow A entersthe first terminal end 202 of wire 200 and flows through the firstterminal of each of the one or more LEDs 100, LED chip 102A may activateand/or power on. Conversely, when the direction of power flow A isreversed to enter the second terminal end 202 of wire 200 and flowthrough the second terminal of each of the one or more LEDs 100, LEDchip 102B may activate and/or power on.

FIG. 8 depicts an LED tree 800 according to one or more aspects of thedisclosure. LED tree 800 may be configured for indoor and/or outdoor useand may be configured to stand upright, to be inserted into a support(e.g., ground, bush, tree, flower arrangement, etc.), and/or hang fromany of a plurality of objects including, but not limited to, a housefaçade, tree, bush, door frame, wall, ceiling, and the like. LED tree800 may include one or more LEDs 100, each of which comprising theabove-mentioned components (e.g., at least LED chips 102A and 102B,casing 104, at least first terminal 106 and second terminal 108), wire200, power terminal 300, and housing apparatus 500. Additionally, eachcomponent of LED tree 800 may have some or all of the structuralcomponents described above in regard to LED system 400.

Wire 200 and each of the one or more LEDs 100 may be included withinsupport apparatus 500. Support apparatus 500 may be made of plastic,metal, or a combination thereof and may include a trunk portion 502,branch portions 504 attached to the trunk portion 502, and twig portions506 attached to the branch portions 504. In some instances, the trunkportion 502 of support apparatus 500 may be a rigid body offeringminimal pliability. The branch portions 504 may be attached to the trunkportion 502 and may be semi-rigid members allowing for bending and/orpositioning. The twig portions 506 may be attached to the branchportions 504 and may be flexible members allowing for additional bendingand/or positioning. However, in certain embodiments, twig portions 506may not be attached to branch portion 504. The trunk portion 502, branchportions 504, and twig portions 506 of support apparatus 500 may all berigid, semi-rigid, or flexible members.

The LEDs 100 included within support apparatus 500 may be of a similartype (e.g., miniature, low-current, low-power, high-power, flashing,bi-color, tri-color, etc.) or may be any of a range of types. Thepattern of LED types of the LEDs 100 of LED tree 800 may be homogeneous(e.g., high-power, high-power, etc.), heterogeneous and symmetric (e.g.,flashing, high-power, high-power, flashing, etc.), heterogeneous andasymmetric (e.g., high-power, high-power flashing, bi-color, tri-color,tri-color, high-power, flashing, etc.), or heterogeneous and random(e.g., high-power, flashing, bi-color, tri-color, etc.).

Furthermore, the pattern of LED types of LEDs 100 may be determinedbased on the portion of support apparatus 500 in which they arecontained (e.g., trunk portion 502, branch portion 504, and twig portion506). For example, LEDs 100 included within trunk portion 502 may be ofa first type (e.g., high-power), LEDs 100 included within branchportions 504 may be of a second type different than the first type(e.g., low-power), and LEDs 100 included with twig portions 506 may beof a third type different from the first and second types (e.g.,flashing).

Additionally, the pattern of LED wavelength profiles for each LED chip102A and 102B of LEDs 100 in LED tree 800 may be determined based on theportion of support apparatus 500 in which they are contained. Forexample, LED chips 102A of LEDs 100 in trunk portion 502 may beconfigured to emit light of a first color (e.g., red), LED chips 102A ofLEDs 100 in branch portions 504 may be configured to emit light of asecond color different than the first color (e.g., green), and LED chips102 of LEDs 100 in twig portions 506 may be configured to emit light ofa third color different than the first and second colors (e.g., white).

While not explicitly shown in FIG. 8 and FIG. 9, LED chips 102A and 102Bmay be included in the one or more LEDs 100. The LED chips of the one ormore LEDs 100 may be configured to activate and/or power on when powerflow A traverses wire 200. For example, when power flow A enters thefirst terminal end 202 of wire 200 and flows through the first terminalof each of the one or more LEDs 100, LED chip 102A may activate and/orpower on. Conversely, when the direction of power flow A is reversed toenter the second terminal end 202 of wire 200 and flow through thesecond terminal of each of the one or more LEDs 100, LED chip 102B mayactivate and/or power on.
